Parameterized the cc.librarySdkMemberType to allow it to support
both static and shared libraries. Created two instances, one for shared
and one for static libraries. A follow up change will add support for
libraries that can be both.
Added *librarySdkMemberType to nativeMemberInfo as information from
there is needed when generating the snapshot.
Made organizeVariants() func a method of *librarySdkMemberType so that
it can initialize the new field. Moved it to be with all the other
methods of that type.
Added host and device tests for the new module type.
